Question: What is the condition illustrated in this picture?
Answer: Failure of a non-fenestrated biological mesh to integrate with surrounding tissues.
A 76-year old male was electively admitted for recurrent incisional hernia. He had an obstructed umbilical hernia repaired 12 years ago, which became complicated with a persistent sinus. The infected mesh was removed and the defect repaired with biological mesh (Collamend) 18 months ago. The hernia recurred and at surgery, a contracted biological mesh encased in a chronic seroma cavity was excised. A large pore synthetic mesh was used to repair the defect applying the sub-lay technique. Collamend is an acellular porcine dermal cross-linked matrix that is now fenestrated to allow tissue in growth (Figure 1).

Retention times for rutin, sutherlandin A, sutherlandin B, kaempferol-3-O-rutinoside, sutherlandin C, sutherlandin D, quercitrin, quercetin and kaempferol were 11.9, 12.7, 13.8, 15.3, 16.2, 17.0, 18.0, 26.2 and 28.1 minutes, respectively.
